MX887PHTTR Equivalent & Substitute Parts

Part Overview

The MX887PHTTR is an omnipolar Hall Effect magnetic switch manufactured by IXYS Integrated Circuits Division, housed in a TSOT-23-3 package. This component functions as a digital switch with push-pull output, designed to detect magnetic fields from both north and south poles. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the MX887PHTTR must satisfy the following criteria based on allowed electrical and mechanical parameters:

Physical Compatibility:

• Package type: TO-236-3, SC-59, or SOT-23-3 (surface mount, three-pin configuration)
• Mounting type: Surface mount

Functional Compatibility:

• Technology: Hall Effect magnetic sensing
• Function: Omnipolar switch (detects both north and south magnetic poles)
• Polarization: North Pole and South Pole detection capability

Electrical Compatibility:

• Supply voltage range: Must overlap with 2.5V ~ 5.5V
• Operating temperature range: Must cover -40°C ~ 85°C
• Output configuration: Push-pull or equivalent output structure
• Current specifications: Supply current and output current within acceptable operating margins

The TLE4913HTSA1 meets these substitution criteria through matching package geometry, omnipolar Hall Effect technology, overlapping supply voltage range, and identical operating temperature specification.

Parameter Comparison

Engineering Selection Recommendations

The TLE4913HTSA1 is the designated manufacturer-recommended substitute for the obsolete MX887PHTTR. Both components share identical package geometry (TO-236-3/SC-59/SOT-23-3), omnipolar Hall Effect technology, and operating temperature range (-40°C ~ 85°C). Both are ROHS3 compliant and REACH unaffected.

The TLE4913HTSA1 offers the advantage of active product status with automotive-grade qualification (AEC-Q100) and temperature compensation features. The component is currently in production with substantial inventory availability (6100 pcs).

Electrical parameter differences exist: the TLE4913HTSA1 operates at a lower maximum supply current (2.5mA vs. 15µA) and lower maximum output current (2mA vs. 5mA), with slightly different sensing thresholds (±5mT trip vs. ±6mT trip). The output configuration differs (open drain vs. push-pull), requiring circuit-level evaluation for compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the TLE4913HTSA1 directly replace the MX887PHTTR in existing designs?

A: Physical and functional compatibility is confirmed through matching package type, omnipolar Hall Effect technology, and operating temperature range. However, the output type differs (open drain vs. push-pull), and electrical parameters vary. Circuit-level verification is required to confirm compatibility with existing pull-up resistor networks and load configurations.

Q: What are the key differences in sensing performance?

A: The MX887PHTTR specifies ±6mT trip and ±0.6mT release thresholds. The TLE4913HTSA1 specifies ±5mT trip and ±4.2mT release thresholds. These differences may affect magnetic field detection sensitivity and hysteresis characteristics in specific applications.

Q: Are both components available in the same package?

A: Both components use the TO-236-3/SC-59/SOT-23-3 package with identical three-pin surface mount configuration, ensuring mechanical compatibility on PCB layouts.

Q: What is the significance of the product status difference?

A: The MX887PHTTR is obsolete and no longer manufactured. The TLE4913HTSA1 is an active product in current production, ensuring long-term availability and supply chain continuity.

Q: Does the TLE4913HTSA1 include additional features?

A: The TLE4913HTSA1 includes temperature compensation and automotive-grade qualification (AEC-Q100), providing enhanced performance stability across temperature ranges and suitability for automotive applications.
